The freediver passed through the 7m-deep passage in the Dos Ojos cave system, using a monofin and handheld torch.
Coste displayed a skilled combination of steady speed and positional control to swim a precise course between close walls, floor and roof.
He was guided by pre-laid lines, and a team of back-up divers stood by in case he fell foul of the cave’s structures or got lost.
He was under water for 2min 32sec.
Guinness World Records is expected to confirm the swim, planned by Coste’s wife and manager Gabriela Contreras, as a new distance record for a cave freedive.
It will be the eleventh world record achieved by Coste, others having been set under the auspices of the sport’s governing body, AIDA, and Guinness.
Coste is a former men’s AIDA depth world record holder in Variable Weight (140m), Constant Weight (105m) and Free Immersion (101m).
He was injured in 2006 while training to break Austrian Herbert Nitsch’s then No Limits record of 183m.
He experienced difficulty with balance, coordination and speech, but recovered after a period in hospital with recompression treatment.
